See My Hovercraft is Full of Eels by Luke Donforth for another mixed CC. I have an unpublished riff off that called Alternative Transport (not near my cards or I'd provide the choreo) which can alternate easily.
And just for another take for swings out of CC, there's this (definitely not beginner friendly) one:
Contraventional Corners (Rev 2) - Becket RIGHT/CCW - Don Veino, Revised 20190329
Your Shadow is past your PNR if facing up/down from hands 4.
A1 Slice Right 1+1/2x (forward on right diag. until NEW GENTS are face to face, fall straight back)
Gents Turn 1/2 Reverse Contra Corners (LH w/NBR1 GNT Center, RH with NBR1 LDY)
A2 Gents Turn 1/2 Reverse Contra Corners (LH w/NBR1 GNT Center, RH with NBR2 LDY)
end facing back along side to NBR1 Swing
B1 NBR1 Promenade Across (Past PNR) and tight Courtesy Turn to face across
(end so Ladies are directly opposite each other like the Gents were)
Ladies Turn 1/2 Contra Corners (RH w/NBR1 LDY, LH with PNR)
B2 Ladies Turn 1/2 Contra Corners (RH w/NBR1 LDY, LH with Shadow)
end facing back along side to PNR Swing
First time through could be on slight right diagonal (Slice 1/2x) so original foursome gents start the A1 CC, with ghost corners for the 2s.
